Earphone

This application claims the priority benefit of Taiwan application serial no. 113151074, filed on Dec. 27, 2024. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.

The disclosure relates to an earphone.

When the modern earphone is worn on the ear, the supporting structure of the earphone only slightly rests on the edge of the cavum conchae of the ear, and cannot stably engage with the ear. Therefore, in more vigorous activity scenarios (for example, sports, wearing a hat, arranging hair, etc.), the earphone is prone to falling off the ear due to the accidental touch or the unexpected force, resulting in poor wearing stability of the earphone.

The disclosure provides an earphone with the better wearing stability.

The earphone of the disclosure is adapted to be worn on an ear. The earphone includes a wearing component and an acoustical component. The wearing component includes a rear positioning portion and an acoustic channel. The acoustical component is connected to the wearing component, and the acoustical component includes an acoustic chamber. The acoustic chamber is communicated with the acoustic channel. When the earphone is worn on the ear, the wearing component is located in a cavum conchae of the ear, the rear positioning portion exerts a positioning force on a rear edge of the cavum conchae, thereby positioning the earphone on the ear. The acoustic channel corresponds to an ear canal of the ear.

Based on the above, when the earphone of the disclosure is worn on the ear, the rear positioning portion of the wearing component exerts the active positioning force on the rear edge of the cavum conchae, so that the earphone is stably positioned on the ear, providing the earphone with the better wearing stability. At this time, the acoustic channel of the wearing component corresponds to the ear canal, so that the distance between the acoustic sound output channel and the ear canal is shorter, thereby reducing the degree of the signal energy attenuation from the earphone enters the ear canal, and improving the audio experience and the audio performance of the earphone.

The rear edgeconnects between the cymba conchaeand the bottom edge, and faces the tragusof the ear. The traguscovers the ear canalof the ear. When the earphoneis worn on the ear, the wearing componentis positioned in the cavum conchaeof the ear. The rear positioning portionexerts a positioning force F on the rear edgeof the cavum conchaeto position the earphoneon the ear. The positioning force F specifically is a frictional force or a deformation force, but not limited thereto. The positioning force F may be parallel to the extension axis L, but not limited thereto.

212 213 210 200 200 212 213 240 200 The resting structure of the known earphone conforms to the cymba conchaeor the bottom edgeof the cavum conchae, passively resting on the ear. Therefore, when the known earphone is accidentally touched or subjected to the unexpected force, the known earphone may easily fall off the earand lack stability. The resting structure of the known earphone needs to form a specially protruding structure to conform to the cymba conchaeor the bottom edge, thereby increasing the volume of the earphone, making the known earphone inconvenient for storage and wearing. The known earphone may also engage with the helixof the earthrough the structure such as the ear hook, further increasing the volume of the earphone.

Therefore, the earphoneis stably positioned in the earand not leave the eardue to the accidental touch or the unexpected force, thus improving the wearing stability of the earphone. The rear positioning portionof the earphoneis located on the extension axis Lof the wearing component, thereby further reducing the volume of the earphone.

When the earphoneis worn on the ear, since the wearing componentof the earphoneextends into the cavum conchaeof the ear, the sound output surfaceof the earphonefaces the ear canalof the ear, making the acoustic channelcorrespond to the ear canal, and closer to the ear canal inletof the ear canal, thereby shortening the distance between the acoustic channeland the ear canal. The degree of the signal energy attenuation of the audio from the earphoneentering the ear canalis reduced due to the shorter distance between the acoustic channeland the ear canal, thereby improving the audio experience and the audio performance of the earphone.

The front positioning portionis located on the extension axis Lof the wearing component, but not limited to this. When the earphoneis worn on the ear, the front positioning portionextends into the cavum conchaeand is covered by the tragusof the ear. The front positioning portionis positioned between the ear canaland the tragusand abuts against the ear. Thereby, the earphoneis more stably connected to the ear.

The support componentis detachably and replaceably connected to the wearing body, but not limited thereto. The support componentincludes a support body, a rear positioning portion, and a front positioning portion. The acoustical componentis connected to a surfaceof the wearing bodyopposite to the sound output surface. The wearing bodyincludes a slot, and the support bodyof the support componentincludes a connecting openingand a protrusion. The protrusionextends from an edge of the connecting openingtowards a center of the support body. The wearing bodymay enter the connecting opening, causing the protrusionto engage with the slot, thereby connecting the support component(the support body) to the wearing body.

Two ends E, Eof the rear positioning portionare connected to the other side of the support body, forming a hollow structure G between the rear positioning portionand the support body. In this embodiment, the material of the support componentis a soft material, and the support bodyand the rear positioning portionare integrally formed, but not limited threreto.

As shown in, since the hollow structure G between the rear positioning portionand the support body, when the earphoneis worn on the ear, the rear positioning portionmay be pressed and deformed by the cavum conchaeto generate the positioning force F, actively abutting against the rear edgeof the cavum conchae. The earphoneis adapt to earsof different shapes through the deformation of the rear positioning portion, thereby improving the usability of the earphoneand enhancing the connection strength between the earphoneand the ear.

In an embodiment not shown, there may be no hollow structure G between the rear positioning portionand the support body, and when the earphoneis worn on the ear, the rear positioning portionmay still deform to generate the positioning force F. In an embodiment not shown, the front positioning portionmay have the same structure as the rear positioning portion. In an embodiment not shown, the material of the support componentmay be a non-soft material. In this embodiment, an extension axis Lof the acoustical componentis different from the extension axis Lof the wearing component, causing the acoustical componentto be inclinedly connected to the wearing component, but not limited thereto. In an embodiment not shown, the earphonemay be a true wireless stereo (TWS) earphone.

Please refer toandat the same time, the earphoneof this embodiment is similar to the previous embodiment. The difference between the two is that the support bodyof the wearing componentin this embodiment has a longer length, making a length Wof the support componentalong the extension axis Llonger. The length Wof the support componentinis greater than a length Wof the support componentin, allowing the earphoneof this embodiment to better adapt to ears of different shapes. The earphoneof this embodiment has the same effect as the previous embodiment, and is not repeated herein.

In summary, when the earphone of the disclosure is worn on the ear, the rear positioning portion of the wearing component exerts the active positioning force on the rear edge of the cavum conchae, so that the earphone is stably positioned on the ear, providing the earphone with the better wearing stability. At this time, the acoustic channel of the wearing component corresponds to the ear canal, so that the distance between the acoustic sound output channel and the ear canal is shorter, thereby reducing the degree of the signal energy attenuation from the earphone enters the ear canal, and improving the audio experience and the audio performance of the earphone.
